1. Emission and Deposit Formation in Direct Injection Stratified Charge SI Engines
Abstract : A promising approach to increase the efficiency of the spark ignition (SI) engine is to inject the fuel directly into the cylinder to form a stratified charge. There is a potential to reduce the fuel consumption at low speeds and loads by 20 - 25% compared with conventional SI engines with stoichiometric homogeneous charge. READ MORE

3. Challenges and Advantages of Stratified Combustion in Gasoline Direct-Injected Engines
Abstract : The modern world is based on an extensive transport network in which passenger vehicles play a major role. Although passenger vehicles have improved significantly in recent decades, they still contribute to the pollution of our environment and global warming. Consequently, new ways of reducing their emissions are needed. READ MORE

5. Optical Diagnostics Applied to Internal Combustion Engines: Catalysis, Sprays and Combustion
Abstract : Gasoline direct injection with spray-guided charge formation is one of the most promising concepts to reduce fuel consumption and CO2 emissions of spark ignited engines. The advantages with the system are owing to un-throttled operation and stratification of the injected fuel resulting in a globally lean combustion. READ MORE
